Title: Information transmission system using pulse wave having multifrequency value
Inventor: MIURA AYAO
IPC: H04L27/10
Filed: 1985-12-16
Abstract: PURPOSE:To narrow an occupied band width and to transmit the information at high speed by allowing a frequency value and the information to be transmitted to correspond to each other specifically and storing and accumulating a modulated wave for a proper time to equalize its phase to the phase of a carrier. CONSTITUTION:The modulated wave is stored and accumulated for a proper time and is taken in synchronously with the phase of the carrier, and a frequency value wave corresponding to this modulated wave information is generated as the pulse wave of one period which starts with 0 deg. phase angle and ends with 360 deg. accurately. One-period components of frequency value wave corresponding to following modulated wave information are generated without delay, and the point of 360 deg. of the preceding period and the point of 0 deg. of the current period are connected accurately. Pulse waves each of which corresponds to one period are connected momently to generate a transmission wave continuously. As the result, this transmission wave realizes an ideal distortionless FM wave which is not modulated on the way of one period while continuing in phase and has a precise instantaneous frequency value though changing with respect to phase.

IPC: H04N5/232
Filed: 1991-10-29
Abstract: PURPOSE:To make possible the optimum amount of contour correction without lowering resolution with the enlargement of a picture by controlling a digital signal processing corresponding to the magnification information of an electronic zoom. CONSTITUTION:When converting an input video signal to a digital signal at an A/D conversion part 1, afterwards, inputting the signal to a DSP block 2 and executing the contour correction, the magnification information is inputted from a microcomputer 6 for electronic zoom control to a microcomputer 5 for DSP control. After the information is set and controlled so as to gradually enlarge the correcting amount with the increase of magnification, the information is inputted to an electronic zoom processing block 3, processed together with luminance signals and chrominance signals and outputted through a D/A. Thus, the resolution is prevented from being lowered in case of enlargement by varying the contour correcting amount corresponding to the enlargement scale of the picture.

CONSTITUTION:Piezoelectric porcelains 10 (11) polarizing so as to be aligned to electrodes 3 are mounted on a facing electrode 7. Pressure matched to the external diameter and the thickness of the piezoelectric porcelain is selected and applied. Since a point electrode 1 is a contact pin type, the pressure larger than the pressure in the pin is not applied, a biased load is not generated, and electric continuity also is sufficiently obtained. Next, a specified voltage according to the thickness of the piezoelectric porcelain is applied for a specified period, and discharging is performed for a specified period after the voltage is released. Then the pressure is removed. Thereby it is unnecessitated to exchange the electrode in response to the difference of the external diameters of the piezoelectric porcelains 10 (11), and simultaneous polarization of a plurality of the piezoelectric porcelains can be realized.

Title: Surface contour measurement device
Inventor: TAKABAYASHI HITOSHI
IPC: G01B11/00
Filed: 1994-10-25
Abstract: PURPOSE:To take measurements at high-speed, continuously and with high precision by providing a Z-axis direction displacement amount detector, a height signal output memory device, a Z-axis direction displacement amount control device, an adder device or the like for offsetting disagreement in a tracking displacement amount. CONSTITUTION:A height signal from an optical sensor and a Z-axis direction displacement amount are added by an adder device 126. As a height signal from the optical sensor is displaced by an amount corresponding to a Z-axis direction tracking error for the irregularities of measurement object surface, and an output signal from the detector 15 is displaced in a direction opposite to the displacement of the optical sensor, a tracking error is offset by the addition of both displacement amounts with the device 126. As a result, even when the tracking of the irregularities of the object surface with the optical sensor in the Z-axis direction is not complete, highly precise measurements can always be taken. In addition, highly precise measurements with an X-Y table under high-speed travel can be taken, because of compensation with the addition.

Abstract: PURPOSE:To eliminate the need for the reproduction of a new sheet even though the registered information is changed by providing a sheet type pressure sensor on the display screen of a thin display device and therefore easily retrieving the desired information to be inputted out of those registered information. CONSTITUTION:An operator hits either one of displayed page numbers over a sheet type pressure sensor 2 via a stylus pen 6. Thus the sensor 2 detects the pressed point. Receiving the detection information, a control part 4 recognizes an area where the detected point is included and reads the information on the corresponding page out of a register information storage part 5 to display it on a thin display part 1. Then the operator selects and hits either one piece of displayed information. Thus the selected information is detected by the sensor 2 in the same manner as the selection of pages. Then the corresponding information is read out of the part 5 and used as the cad input information. Thus, the desired information can be retrieved in a short time and its is not required to produce a sheet again even when the registered contents are changed.

Title: Image forming device
Inventor: ITO TAKASHI
IPC: G03G15/00
Filed: 1992-09-30
Abstract: PURPOSE:To restrict a developing gap, exposure position and focal distance of an exposure head at a high precision by retaining the spacing between a developing sleeve and a photosensitive drum by a pair of restriction rollers disposed in a space where the two members are faced to each other. CONSTITUTION:The pair of restriction rollers 41 and 42 are disposed in the space where the developing sleeve 7 and the photosensitive drum 1 are faced to each other in a cross sectional surface at right angle of an axis with the developing position in between and the spacing between the two members is retained by bringing the periphery surfaces of each of the developing sleeve 7 and the photosensitive drum 1 into contact with these restriction rollers 41 and 42. Therefore, even when a variation is generated in a crossing DELTAL1 of the photosensitive drum 1 or the sleeve 7, the developing gap X can be restricted regardless of this. Furthermore, because the space between the photosensitive drum 1 and the sleeve 7 is supported at two points by the pair of restriction rollers 41 and 42 restricted in the direction of the gap with the developing gap X in between, the degree of parallelism between the drum 1 and the photosensitive drum can be maintained in good precision even when the diameter of the photosensitive drum 1 is made smaller. Thus, the exposure and the developing can be maintained in good precision.

Title: Rewritable optical recording medium and its recording method
Inventor: KAWAMURA TATSURO
IPC: G11B7/24047
Filed: 1990-10-22
Abstract: PURPOSE:To facilitate high density recording by a short wavelength light, recording by a low power light, high repeatability characteristics, high transfer rate recording, multivalue recording, etc. by a method wherein recording is performed by the variation of the spatial distribution of particles dispersed in medium. CONSTITUTION:If a recording light is absorbed by particles 1, medium 2, disc substrate 3 and a protective layer 4 and a temperature is elevated, the medium 2 is melted. At that time, the particles 1 are pushed toward an outer circumference direction B by a centrifugal force created by the rotation of a disc. Therefore, if a trench-shaped track 6 is filled with the medium 2 in which the particles 1 are uniformly dispersed and the recording light is applied to a pit in the track 6 and then the recording light is taken off while the medium 2 is in the melted state, the recording is completed. At the time of reproduce, a reproducing light whose power is not so strong as to melt the medium 2 is applied and a transmitted light or a reflected light is detected to reproduce the record. With this constitution, an optical recording medium which facilitates high density recording by a short wavelength light, recording by a low power recording light, high repeatability characteristics, high transfer rate recording, multivalue recording, etc. can be obtained.
